The Lowdown
Alright, grab your board. The next couple of weeks are looking pretty tasty around here, with a proper pulse of long-period SW groundswell setting up. Gotta be smart about the windows though, because the winds are gonna be all over the place. Let's break it down.
We're starting off on Saturday the 8th with a small, clean 1ft bump, but there's no real energy in it. It’s a bit of a tease, better to just wait it out.
Come Sunday morning the 9th, it starts to get interesting. The swell jumps to a solid 7ft from the SSW with a long 14-second period. The wind is dead glassy, and that combo is pure magic. This is the standout window, hands down. The wave energy is strong too, hitting 1534. This one’s for the experienced crew, with that size and push.
The next several days keep the swell pumping. Monday the 10th has 7-8ft surf from the south, but the wind is messy, chopping things up. Tuesday the 11th is a much better bet. It's 8ft in the morning and pushing 8ft in the afternoon, still from the S at 13 seconds, with light cross-offshore winds keeping it clean. Another excellent window for the experts, energy is over 2000 on the afternoon.
Wednesday the 12th holds in the 7-8ft range, but the wind is a bit stronger. Thursday the 13th sees a slight drop to 6-6ft, but the wind is offshore in the morning, so it should be clean and fun.
Then we get what might be the pick of the week. Friday morning the 14th. The swell is still a solid 7ft from the S with a 14-second period, and the wind is absolute zero. Glassy as can be. The wave energy is a strong 1492. This will be perfection. Don't sleep on it because the afternoon wind is onshore gunk.
The weekend of the 15th and 16th drops down a notch in size to 5-6ft, with glassy conditions on Sunday the 16th morning. That'll be a fun, clean option.
The swell fades out for a few days from the 17th to the 20th, with leftover energy and wind blowing all over the shop. There are some clean windows but the size drops to 3-5ft.
There's a cool little pulse for the very end of the forecast period. On Friday the 21st, the swell is tiny at 2ft, but it’s a 16-second groundswell with glassy conditions. It's small, but might offer a clean, long-period nugget on the right bank.
After that, it looks like it's gonna get blown out and messy. The good stuff from the 9th to the 14th is your best bet. Big, clean, and powerful. Make sure you're out there for the morning sessions, especially Sunday the 9th and Friday the 14th.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
